4.5-B GASDRY PEAK DESICCANT
The general purpose tablet is reccommended for installations where
inlet gas temperature is 80
o F or lower. Depending on the pressure and
temperature, GasDry Peak can provide a residual moisture content
below 5 lbs/MMSCF.
Chart 3 shows the level of dryness that GasDry Peak provides at
different conditions.
Chart 4 shows an approximate consumption rate for GasDry Peak
at several conditions. Use the charts for guidelines to calculate the
approximate consumption rate of the desiccant.

4.5-B GASDRY MAX DESICCANT
Where extremely dry gas is required or where operating pressure is
low, GasDry Max tablets provide a lower residual moisture content.
Chart 5 shows the level of dryness that GasDry Max will provide at
different conditions.
Chart 6 shows an approximate consumption rate for GasDry Peak
at several conditions. Use the charts for guidelines to calculate the
approximate consumption rate of the desiccant.
